Application Examples
This chapter describes possible applications for the different valve types. Of
course there are also other applications possible which are not listed here.
Valve Positions
The eluent flows through the sample loop in opposite direction of the position
load (see arrows in the figures).
1. The sample loop is filled by injecting the sample at port 1. The sample runs
into the sample loop (port 2 and 5) and excessive sample is transported into
the waste container through port 6.
2. The valve is switched from load to inject.
3. The pump (port 4) transports the sample to the column (port 3).
4. The eluent flows through the sample loop in opposite direction then during
injection, see arrows in the figures.
Valve Position Load (L)
